However, the transmission efficiency of the self-locking mechanism is low, and when the motor fails, the brake cannot be released immediately, which poses a safety problem.

Brake pads and calipers, or, one uses a friction assembly and the other uses a brake caliper. In the following embodiments, both the service brake assembly and the parking brake assembly are explained by taking friction assemblies that can increase friction to the braked object as examples.

实施例一、Embodiment 1

本实施例提供一种集成行车和驻车制动的制动装置，参见图1和图2所示，制动装置包括：行车制动机构10和驻车制动机构20。This embodiment provides a braking device that integrates service and parking brakes. As shown in FIGS. 1 and 2 , the braking device includes: a service brake mechanism 10 and a parking brake mechanism 20 .

行车制动机构10包括：行车驱动组件11，行车传动组件12以及行车制动组件13。行车驱动组件11具有能够输出动力的动力输出端，行车传动组件12连接在行车驱动组件11的动力输出端，行车制动组件13与行车传动组件12连接。行车驱动组件11用于通过行车传动组件12驱动行车制动组件13在第一制动位A和第一解除位B之间切换。在第一制动位A，行车制动组件12用于对车辆本体的刹车盘本体进行制动。在第一解除位B，行车制动组件12用于解除对车辆本体的刹车盘本体的制动。The service brake mechanism 10 includes: a service drive component 11 , a service transmission component 12 and a service brake component 13 . The traveling driving assembly 11 has a power output end capable of outputting power. The traveling transmission assembly 12 is connected to the power output end of the traveling driving assembly 11 . The traveling braking assembly 13 is connected to the traveling transmission assembly 12 . The service drive assembly 11 is used to drive the service brake assembly 13 to switch between the first braking position A and the first release position B through the service transmission assembly 12 . In the first braking position A, the service brake assembly 12 is used to brake the brake disc body of the vehicle body. In the first release position B, the service brake assembly 12 is used to release the brake on the brake disc body of the vehicle body.

本实施例中，行车制动组件13可采用单个向车辆本体的刹车盘本体增加摩擦力的摩擦组件实现，该单个摩擦组件例如可以是刹车片。在第一制动位A，刹车片接触车辆本体的刹车盘本体，并对刹车盘本体产生摩擦力，从而对刹车盘本体进行制动。在第一解除位B，刹车片远离刹车盘本体，从而解除对刹车盘本体的制动。可以理解的是，对刹车盘本体的制动的制动力的大小是相对变化的，例如，车辆本体在行驶状态且需要减速时的制动力小于车辆本体由行驶状态转换为停止行驶时的制动力。图1中双向箭头所指示的AB方向仅用于表示第一制动位A时行车制动组件13的移动方向、以及第一解除位B时行车制动组件13的移动方向。In this embodiment, the service brake component 13 can be implemented by a single friction component that adds friction to the brake disc body of the vehicle body. The single friction component can be, for example, a brake pad. In the first braking position A, the brake pad contacts the brake disc body of the vehicle body and generates friction force on the brake disc body, thereby braking the brake disc body. In the first release position B, the brake pads move away from the brake disc body, thereby releasing the brake on the brake disc body. It can be understood that the magnitude of the braking force applied to the brake disc body changes relatively. For example, the braking force when the vehicle body is in a driving state and needs to decelerate is less than the braking force when the vehicle body changes from a driving state to a stopped driving state. . The AB direction indicated by the two-way arrow in Figure 1 is only used to indicate the moving direction of the service brake assembly 13 in the first braking position A and the moving direction of the service brake assembly 13 in the first release position B.

当然，在其他实施例中，行车制动组件13也可采用制动卡钳对刹车盘本体增加摩擦力的方式实现。Of course, in other embodiments, the service brake assembly 13 can also be implemented by using a brake caliper to increase friction on the brake disc body.

驻车制动机构20包括：驻车驱动组件21和驻车制动组件22，驻车驱动组件21用于驱动驻车制动组件22在第二制动位C和第二解除位D之间切换。在第二制动位C，驻车制动组件22对行车传动组件12进行制动。在第二解除位D，驻车制动组件22解除对行车传动组件12的制动。The parking brake mechanism 20 includes: a parking drive assembly 21 and a parking brake assembly 22. The parking drive assembly 21 is used to drive the parking brake assembly 22 between the second braking position C and the second release position D. switch. In the second braking position C, the parking brake assembly 22 brakes the service transmission assembly 12 . In the second release position D, the parking brake assembly 22 releases the brake on the service transmission assembly 12 .

本实施例中，设置有两个驻车制动机构20，两个驻车制动机构20分别相对称的设置在行车传动组件12的两侧，换言之，驻车制动组件22对行车传动组件12的两个相对位置进行制动，可有效平衡制动，并保证制动力稳定。In this embodiment, two parking brake mechanisms 20 are provided, and the two parking brake mechanisms 20 are respectively symmetrically arranged on both sides of the driving transmission assembly 12. In other words, the parking brake assembly 22 is opposite to the driving transmission assembly 12. Braking at two relative positions of 12 can effectively balance braking and ensure stable braking force.

本实施例中，驻车制动组件22同样可采用单个向行车传动组件增加摩擦力的摩擦组件实现，该单个摩擦组件例如同样也可以是刹车片。如图1所示，在第二制动位C，刹车片接触行车传动组件12，并对行车传动组件12产生摩擦力，从而对行车传动组件12进行制动。如图2所示，在第二解除位D，刹车片远离行车传动组件12，从而解除对行车传动组件12的制动。该实施方式中，通过驻车驱动组件21驱动驻车制动组件22处于第二制动位C时的制动力大小是恒定不变的。图1中双向箭头所指示的CD方向仅用于表示第二制动位C时驻车制动组件22的移动方向、以及第二解除位D时驻车制动组件22的移动方向。In this embodiment, the parking brake component 22 can also be implemented by a single friction component that adds friction to the driving transmission component. The single friction component can also be a brake pad, for example. As shown in FIG. 1 , in the second braking position C, the brake pad contacts the traveling transmission assembly 12 and generates friction force on the traveling transmission assembly 12 , thereby braking the traveling transmission assembly 12 . As shown in FIG. 2 , in the second release position D, the brake pads move away from the traveling transmission assembly 12 , thereby releasing the brake on the traveling transmission assembly 12 . In this embodiment, the braking force when the parking brake assembly 22 is driven by the parking drive assembly 21 to be in the second braking position C is constant. The CD direction indicated by the double-headed arrow in FIG. 1 is only used to indicate the moving direction of the parking brake assembly 22 in the second braking position C and the moving direction of the parking brake assembly 22 in the second release position D.

当然，在其他实施例中，驻车制动组件22同样也可采用制动卡钳对行车传动组件12增加摩擦力的方式实现。Of course, in other embodiments, the parking brake assembly 22 can also be implemented by using a brake caliper to increase friction on the driving transmission assembly 12 .

一些实施例中，行车制动组件13和驻车制动组件22中，其一可采用能够对被制动物（刹车盘本体或者行车传动组件13）增加摩擦力的单个摩擦组件（如，刹车片），另一可采用制动卡钳。In some embodiments, one of the service brake assembly 13 and the parking brake assembly 22 may use a single friction component (such as a brake pad) that can increase friction on the braked object (the brake disc body or the service transmission assembly 13). ), the other can use brake calipers.

本申请中，当车辆本体正常行驶过程中由高速行驶状态切换至低速行驶状态时，行车驱动组件11通过行车传动组件12驱动行车制动组件13处于第一制动位A，对刹车盘本体施加摩擦力以产生制动力、进而进行制动，其中，该制动力的大小能够使得车辆本体减速，例如，车辆本体由50km/h减速为40km/h。当车辆本体由行驶状态切换为停止状态时，行车驱动组件11通过行车传动组件12驱动行车制动组件13处于第一制动位A，对刹车盘本体施加摩擦力以产生制动力、进而进行制动，其中，该制动力的大小能够使得行驶状态的车辆本体停止行驶，例如，车辆本体由25km/h减速为0km/h。当车辆本体需要产时间停止行驶（驻车）时，行车驱动组件11通过行车传动组件12驱动行车制动组件13处于第一制动位，对刹车盘本体施加摩擦力以产生制动力，进而进行制动，其中，该制动力的大小能够保证由车辆本体由行驶状态切换为停止状态，并保持在停止状态下的刹车盘本体不会随车辆本体的车轮本体的转动而转动。在车辆本体停止行驶的同时，驻车驱动组件21驱动驻车制动组件22处于第二制动位C，对行车传动组件12施加摩擦力以产生制动力，进而进行制动，其中，该制动力的大小能够保证在任何状态下行车传动组件12始终处于停止工作的状态，通过驻车制动组件22从而达到对行车传动组件12辅助制动的目的。相较于以往采用电机堵转的方式，可有效提高安全性。如此，形成集成行车制动和驻车制动的制动装置，不仅结构简单、紧凑，可有效节省占用空间，还能够有效提高使用安全性。In this application, when the vehicle body switches from a high-speed driving state to a low-speed driving state during normal driving, the service drive assembly 11 drives the service brake assembly 13 through the service transmission assembly 12 to be in the first braking position A, exerting force on the brake disc body. Friction is used to generate braking force and then brake. The magnitude of the braking force can decelerate the vehicle body. For example, the vehicle body decelerates from 50km/h to 40km/h. When the vehicle body switches from the driving state to the stopped state, the service driving assembly 11 drives the service brake assembly 13 to the first braking position A through the service transmission assembly 12, and applies friction force to the brake disc body to generate braking force, thereby braking. The braking force is large enough to stop the vehicle in a driving state. For example, the vehicle decelerates from 25km/h to 0km/h. When the vehicle body needs time to stop driving (parking), the service drive assembly 11 drives the service brake assembly 13 to the first braking position through the service transmission assembly 12, and applies friction to the brake disc body to generate braking force, and then the vehicle is in the first braking position. Braking, where the magnitude of the braking force can ensure that the vehicle body is switched from a driving state to a stopped state, and the brake disc body maintained in the stopped state will not rotate with the rotation of the wheel body of the vehicle body. While the vehicle body stops traveling, the parking drive assembly 21 drives the parking brake assembly 22 to the second braking position C, exerting friction force on the driving transmission assembly 12 to generate braking force, and then brake. The magnitude of the power can ensure that the driving transmission assembly 12 is always in a stopped working state under any condition, and the purpose of auxiliary braking of the driving transmission assembly 12 is achieved through the parking brake assembly 22 . Compared with the previous method of motor stalling, safety can be effectively improved. In this way, a braking device that integrates the service brake and the parking brake is formed, which not only has a simple and compact structure, but can effectively save space, and can also effectively improve the safety of use.

当行车制动组件13在第一制动位A时，行车驱动组件11通过行车传动组件12使行车制动组件13可产生第一制动力。在车辆本体进行长时间制动但不停止行驶（例如，车辆本体长下坡）时，处于第一制动位A的行车制动组件13产生第一制动力，驻车制动组件22处于第二制动位C。可以理解的是，该第一制动力的大小能够保证车辆本体的刹车盘本体在不被完全制动的状态下，还能够保证车辆本体处于低速行驶状态。该第一制动力是由行车驱动组件11进行控制的，通过驻车制动组件22对行车传动组件12的作用，从而行车传动组件12能够保持在使得行车制动组件13产生第一制动力的状态，可在不通过行车驱动组件11驱动的前提下，保持行车制动组件13处于产生第一制动力的状态。When the service brake assembly 13 is in the first braking position A, the service drive assembly 11 enables the service brake assembly 13 to generate the first braking force through the service transmission assembly 12 . When the vehicle is braking for a long time but does not stop driving (for example, the vehicle is going downhill), the service brake assembly 13 in the first braking position A generates the first braking force, and the parking brake assembly 22 is in the third braking position. Second brake position C. It can be understood that the magnitude of the first braking force can ensure that the brake disc body of the vehicle body is not completely braked, and can also ensure that the vehicle body is in a low-speed driving state. The first braking force is controlled by the service drive assembly 11, and through the action of the parking brake assembly 22 on the service transmission assembly 12, the service transmission assembly 12 can be maintained at a position where the service brake assembly 13 generates the first braking force. state, the service brake assembly 13 can be kept in a state of generating the first braking force without being driven by the service drive assembly 11 .

需要说明的是，第一制动力是根据车辆本体在进行长时间制动但不停止行驶时所需的初始行驶速度（进入坡道时的速度）和终止行驶速度（在坡道上需保持的速度）确定的，理想状态下，若坡道上未存在其他车辆，则终止行驶速度保持不变，第一制动力控制车辆本体由初始行驶速度切换为终止行驶速度的力的大小也处于不变的状态。若坡道路况复杂，车辆本体在行驶过程中的终止速度是变化的，则相应的，第一制动力处于变化的状态。It should be noted that the first braking force is based on the initial driving speed (the speed when entering the slope) and the terminal driving speed (the speed that needs to be maintained on the slope) when the vehicle is braking for a long time without stopping. ) is determined. Under ideal conditions, if there are no other vehicles on the slope, the terminal driving speed remains unchanged, and the force used by the first braking force to control the vehicle body to switch from the initial driving speed to the terminal driving speed also remains unchanged. . If the slope road conditions are complex and the terminal speed of the vehicle body changes during driving, the first braking force will be in a changing state accordingly.

当然，若终止行驶速度是保持不变的状态，当处于第二制动位C的驻车制动组件22保持行车制动组件13产生第一制动力时，行车制动组件13可立即或在预设时间（例如，5s）后处于第一解除位B，以解除对刹车盘本体的制动。若终止行驶速度是变化的状态，则处于第二制动位C的驻车制动组件22保持行车制动组件13产生的第一制动力也是变化的，如此，若当前需要较大的终止行驶速度时，则行车驱动组件11通过行车传动组件12驱动行车制动组件13需克服处于第二制动位C的驻车制动组件22对行车传动组件12所产生的制动力。Of course, if the end driving speed remains unchanged, when the parking brake assembly 22 in the second braking position C maintains the service brake assembly 13 to generate the first braking force, the service brake assembly 13 can immediately or After a preset time (for example, 5s), it is in the first release position B to release the brake on the brake disc body. If the end travel speed changes, the first braking force generated by the parking brake assembly 22 in the second braking position C to maintain the service brake assembly 13 also changes. In this way, if a larger end travel speed is currently required When the speed is high, the service drive assembly 11 drives the service brake assembly 13 through the service transmission assembly 12 and needs to overcome the braking force generated by the parking brake assembly 22 in the second braking position C on the service transmission assembly 12.

当行车制动组件13在第一制动位A时，行车驱动组件11通过行车传动组件12使行车制动组件13还可产生第二制动力，第二制动力的大小大于第一制动力的大小。在车辆本体进行长时间制动但不停止行驶的过程中，为使车辆本体能够停止行驶时（例如，车辆本体在长下坡过程中需要停止行驶时），处于第一制动位A的行车制动组件13产生第二制动力，驻车制动组件22处于第二制动位C。可以理解的是，该第二制动力的大小能够保证车辆本体的刹车盘本体被完全制动。该第二制动力同样是由行车驱动组件11进行控制的，通过驻车制动组件22对行车传动组件12的作用，从而行车传动组件12能够保持在使得行车制动组件13产生第二制动力的状态，同样，可在不通过行车驱动组件11驱动的前提下，保持行车制动组件13处于产生第二制动力的状态。When the service brake assembly 13 is in the first braking position A, the service drive assembly 11 allows the service brake assembly 13 to generate a second braking force through the service transmission assembly 12. The magnitude of the second braking force is greater than the first braking force. size. When the vehicle itself is braking for a long time but does not stop driving, in order to enable the vehicle itself to stop driving (for example, when the vehicle body needs to stop driving during a long downhill slope), the vehicle is in the first braking position A. The braking assembly 13 generates the second braking force, and the parking brake assembly 22 is in the second braking position C. It can be understood that the magnitude of the second braking force can ensure that the brake disc body of the vehicle body is completely braked. The second braking force is also controlled by the service drive assembly 11. Through the action of the parking brake assembly 22 on the service transmission assembly 12, the service transmission assembly 12 can be maintained at a position such that the service brake assembly 13 generates the second braking force. state, similarly, the service brake assembly 13 can be kept in a state of generating the second braking force without being driven by the service drive assembly 11 .

不难理解，当车辆本体在进行长时间制动但不停止行驶的过程中，为使车辆本体能够停止行驶时，则行车驱动组件11通过行车传动组件12驱动行车制动组件13需克服处于第二制动位C的驻车制动组件22对行车传动组件12所产生的制动力，以使行车制动组件13对刹车盘本体产生第二制动力。It is easy to understand that when the vehicle body is braking for a long time but does not stop driving, in order for the vehicle body to stop driving, the service drive assembly 11 drives the service brake assembly 13 through the service transmission assembly 12 and needs to overcome the situation in the third position. The parking brake assembly 22 in the second braking position C generates a braking force on the service transmission assembly 12, so that the service brake assembly 13 generates a second braking force on the brake disc body.

在车辆本体进行长时间制动且停止行驶时，处于第一制动位A的行车制动组件13产生第二制动力，以对刹车盘本体进行制动，保持刹车盘本体不随车辆本体的车轮的转动而转动。并且，驻车制动组件22处于第二制动位C，以对行车传动组件12进行制动。When the vehicle body is braked for a long time and stops driving, the service brake assembly 13 in the first braking position A generates a second braking force to brake the brake disc body and keep the brake disc body from following the wheels of the vehicle body. of turning. Furthermore, the parking brake assembly 22 is in the second braking position C to brake the service transmission assembly 12 .

当然，当处于第二制动位C的驻车制动组件22保持行车制动组件13产生第二制动力时，行车制动组件13可立即或在预设时间（例如，5s）后处于第一解除位B，以解除对刹车盘本体的制动。或者，当处于第二制动位C的驻车制动组件22保持行车制动组件13产生第二制动力时，行车制动组件13始终处于第一制动位A。Of course, when the parking brake assembly 22 in the second braking position C keeps the service brake assembly 13 to generate the second braking force, the service brake assembly 13 can be in the third braking position immediately or after a preset time (for example, 5s). 1. Release position B to release the brake on the brake disc body. Alternatively, when the parking brake assembly 22 in the second braking position C keeps the service brake assembly 13 to generate the second braking force, the service brake assembly 13 is always in the first braking position A.

Specifically, the torque output adjustment module is used to adjust and control the travel drive component 11 to output the first output torque or the second output torque. When the torque output adjustment module adjusts and controls the travel drive component 11 to output the first output torque, the travel transmission component 12 drives the service brake assembly 13 to output the first braking force; when the torque output adjustment module adjusts and controls the service drive assembly 11 to output the second output torque, the service brake assembly 13 is driven by the service transmission assembly 12 to output the second braking force. .
