Description
Technical Field
The invention relates to the technical field of electric patrol cars, in particular to an electric patrol car driven by a front-mounted motor.
Background
The electric patrol car is a car type specially designed and developed for patrol and walk-substituting of managers, mainly is a field car, and is divided into two types of open patrol cars and closed patrol cars.
The traditional electric patrol car adopts a mode of driving a motor by a rear wheel and a rear wheel, and the straight-line running performance of the traditional electric patrol car is general; the sensitivity to side wind is high; because the load of the front wheel is small, the steering is difficult when the vehicle runs on the ice surface; obvious oversteer is presented when the vehicle is driven in a turn; luggage space is greatly restricted. If the mode of front-mounted front-wheel drive of the motor is adopted, the passenger space of the electric patrol car is more spacious, the height of the floor is reduced, and the riding comfort is improved; the ability to cross obstacles is high; the operating mechanism is relatively simple; the drive assembly is arranged in front, so that the load of a front shaft can be increased, and the control stability during full-speed running and the direction stability during braking are improved; the rear suspension system is simplified; when the vehicle runs on accumulated snow or slippery road surfaces, the vehicle body is pulled by the front wheels, so that the directional stability is ensured; the trunk is arranged at the rear of the vehicle, and a large enough trunk space is provided.
Along with the development of the electric patrol cars, the market of the electric patrol cars needs to improve the driving comfort of the cars, improve the defect of a rear-wheel driving mode of a motor and increase the diversity of products. The single-mode product can only meet the requirements of part of customers and cannot match all application scenes.
Disclosure of Invention
Aiming at the defects in the prior art, the invention aims to provide an electric patrol car driven by a front-mounted motor and a front-mounted motor.
In order to solve the technical problems, the technical scheme of the invention is as follows: an electric patrol car driven by a front-mounted motor comprises a power system, a chassis, a car body and tires in a basic structure of the car, wherein a motor in the power system, a speed reducer and a differential mechanism in a chassis running system form a power driving assembly, the speed reducer is connected with the motor, the differential mechanism is connected with the speed reducer, a half shaft assembly in a chassis driving system is connected with the differential mechanism, the power driving assembly is arranged at the front part of the electric patrol car and is installed on the car body, the power driving assembly drives the half shaft assembly, and the half shaft assembly drives two front wheels.
In the electric patrol car driven by the front-wheel with the front motor, the power driving assembly is provided with two output ends, and the two output ends are respectively connected with a half shaft assembly.
In the electric patrol car driven by the front-mounted motor and the front-mounted motor, the power driving assembly is vertically arranged, and the speed reducer adopts a speed reducer with a fixed speed ratio.
Compared with the prior art, the invention has the beneficial effects that: the driving comfort, the trafficability and the direction stability of the electric patrol car are improved.
