Abstract
The utility model discloses a drive front axle with a disc brake mode, belongs to the field of improved designs of automobile front axle structures, and solves technical problems that the brake performance is poor, the heat fading performance is obvious, the rain is not easy to be discharged after entering a brake, the maintenance is inconvenient, and the like in prior drive front axles with drum brake modes. The disc brake mode drive front axle comprises a front axle casing, an inner half shaft, a universal joint, a knuckle, a hub, a hub reduction gear and an outer half shaft, wherein the inner half shaft and the outer half shaft are connected through the universal joint, the hub is driven by the outer half shaft through the hub reduction gear, a wheel screw hole is arranged on the hub, and the disc brake mode drive front axle further comprises a brake disc and a disc break, wherein the brake disc is fixed on the hub through fastening bolts, a yielding groove is arranged at a corresponding position of a mounting end face of the break disc and the wheel screw hole, a lug base is arranged on the knuckle, and the disc break is mounted on the lug base of the knuckle. In order to solve the problem of small space, the wheel screw hole and the fastening bolt are designed on a same distribution circle.
Description
Technical field
The utility model relates to a kind of speciality car drive front axle, the design of the whole change of particularly a kind of brake mode of speciality car drive front axle.
Background technology
In the prior art, the brake mode of speciality car drive front axle generally adopts the drum brake mode, and drum brake mechanism is equipped with in its inside.Drum brake mechanism is at frequent glancing impact, and is frequent because of brake shoe brake cheek and brake wheel friction, can produce a large amount of heat.The friction lining temperature raises rapidly, causes friction coefficient to descend, and braking force also descends thereupon.Above-mentioned phenomenon is called the heat fade of drg.If water inlet in the drg also can cause braking force to descend.Therefore, the drum brake mechanism heat dispersion is poor, and character of heat-fading is more obvious, and rainwater is difficult for again discharging after getting into drg, can influence braking performance of automobile equally.
The utility model content
The purpose of the utility model is that the brake performance of solution drum brake mode drive front axle existence is poor; Character of heat-fading is obvious; Rainwater is difficult for again discharging after getting into drg, can influence the shortcoming of braking performance of automobile equally, and for satisfying the requirement of client to drg deceleration and stopping performance stability.Under the basic unmodified prerequisite of axle housing, wheel reduction gear, the semiaxis of original drum brake mechanism drive front axle, the drum brake mechanism drive front axle is designed to the plate disc brake drive front axle.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
The drive front axle of disc type brake mode comprises front axle housing, inner shaft, universal-joint, steering swivel, wheel hub, wheel reduction gear, outer semiaxis; Inner shaft connects through universal-joint with outer semiaxis; Wheel hub is driven by outer semiaxis through wheel reduction gear, and wheel hub is provided with the wheel screw, and it also comprises brake disc and plate disc brake; Said brake disc is fixed on the wheel hub with binding bolt; Brake disc is installed end face and wheel screw corresponding position is provided with slot to make way, and steering swivel is provided with the ear seat, and plate disc brake is installed on the ear seat of steering swivel.
For solving the narrow and small problem in space, wheel screw and binding bolt are designed on same distribution circle.
After adopting this structure; Originally the drive front axle that had the drum brake mode becomes the drive front axle of disc type brake mode, because the revolving part of plate disc brake is a brake disc, is exposed in the air; Be easy to dispel the heat and dry the moisture on the brake disc; Therefore can avoid the drum brake mechanism heat dispersion poor, character of heat-fading is obvious, and rainwater is difficult for the discharge problem after getting into drg.And because not sealing of brake system, the worn-down that therefore brakes is carefully cut and is unlikely to be deposited in the brake, and the centnifugal force of disk type brake can outwards be dished out pollutions such as all water, dust, to keep certain cleaning.Because the disc type brake part is independent outside, be easier to maintenance in addition than drum brakes.
Description of drawings
Below in conjunction with accompanying drawing full utility model is described further.
Fig. 1 is the drive front axle structural representation of disc type brake mode.
Each sign expression among the figure:
1, front axle housing; 2, inner shaft; 3, universal-joint; 4, steering swivel; 5, plate disc brake; 6, brake disc; 7, slot to make way; 8, wheel hub; 9, wheel screw; 10, wheel reduction gear; 11, binding bolt; 12, outer semiaxis.
The specific embodiment
As shown in Figure 1, the drive front axle of disc type brake mode comprises front axle housing 1, inner shaft 2, universal-joint 3, steering swivel 4, wheel hub 8, wheel reduction gear 10, outer semiaxis 12; Inner shaft 2 connects through universal-joint 3 with outer semiaxis 12, and wheel hub 8 is driven by outer semiaxis 10 through wheel reduction gear 10, and wheel hub 8 is provided with wheel screw 9; It also comprises brake disc 6 and plate disc brake 5, and said brake disc 6 usefulness binding bolts 11 are fixed on the wheel hub 8, rotates with wheel hub 8; Brake disc 6 is installed by end face and wheel screw 9 corresponding positions are provided with slot to make way 7; Can reach the purpose of the wheel bolt of stepping down like this, steering swivel 4 is provided with the ear seat, and plate disc brake 5 is installed on the ear seat of steering swivel 4.
For solving the narrow and small problem in space, wheel screw 9 designs on same distribution circle with binding bolt 11.
The utility model is work like this; Power passes to outer semiaxis 12 by inner shaft 1 through universal-joint 3, rotates through wheel reduction gear 10 deceleration strip runner hubs 8, drives the brake disc 6 that is fixed on the wheel hub 8 then and rotates; When wanting glancing impact; Step on brake pedal, the friction lining that at this moment is fixed on the plate disc brake 5 on the steering swivel 4 ear seats can clamp brake disc 6, thereby reaches the purpose of braking.
The utility model substitutes original drum brake with disc type brake, and it is poor to have overcome original drum brake mechanism heat dispersion, and character of heat-fading is obvious, and rainwater is difficult for discharging shortcoming after getting into drg.Make insensitivity good, easy to maintenance, improved vehicle safety.
