Independent suspension mechanism with motor vehicle rear wheels capable of standing and jumping and wheel driving method

Abstract

The invention provides an independent suspension mechanism with motor vehicle rear wheels capable of jumping vertically and a wheel driving method. The mechanism comprises an independent suspension mechanism, the independent suspension mechanism comprises a vehicle body frame. A left swing frame and a right swing frame are arranged at the two sides of the rear portion of the vehicle body frame correspondingly. A left rear bottom fork frame is arranged under the left swing frame; a right rear bottom fork frame is arranged under the right swing frame; rear wheels are arranged in the left rear bottom fork frame and the right rear bottom fork frame; shock absorbers A are arranged between the left rear bottom fork frame and the left swing frame and between the right swing frame and the right rear bottom fork frame; a rear underpinning frame and a front underpinning frame are arranged under the vehicle body frame in a front-back symmetry mode. A plurality of underpinning springs are uniformly arranged between the vehicle body frame and the front underpinning frame as well as between the vehicle body frame and the rear underpinning frame; shock absorbers B are obliquely arranged between the lower portions of the two sides of the vehicle body frame and the upper portion of the inner side of the left swing frame and between the lower portions of the two sides of the vehicle body frame and the upper portion of the inner side of the right swing frame correspondingly. According to the wheel driving method, a double-pulley type power-off switch is arranged, the structure is reasonable,the design is ingenious, the damping performance is high, and wide prospects are achieved.

Description

Technical field [0001] The invention relates to an independent suspension mechanism and a wheel driving method with which the rear wheel of a motor vehicle can jump upright. Background technique [0002] The motor vehicle suspension is supported between the tires and the body, which can alleviate the impact transmitted to the body from uneven roads, and attenuate the resulting tilt, shaking and vibration in the left and right directions, that is, the cushioning effect, to improve the comfort of passengers and reduce Abrasion of the vehicle on the small impact force. Suspension mechanisms are generally divided into three types, namely independent suspension, semi-independent suspension and non-independent suspension. Independent suspension is independent of semi-independent suspension and non-independent suspension because the left and right wheels can jump independently. Therefore, its driving stability, cushioning, and comfort are better. It is the suspension mode used by most ...

Problems solved by technology

Suspension mechanisms are generally divided into three types, namely independent suspension, semi-independent suspension and non-independent suspension. Compared with semi-independent suspension and non-independent suspension, independent suspension is independent of each other because its left and right wheels can jump independently. , so its driving stability, cushioning, and comfort are better. It is the suspension method used by most of the current cars, but the independent suspension structure of the current car is complicated, and it uses a simple centered disconnected suspension. The axle has a limited load, and the beating of the wheels will change its original upright state; at the same time, the structure of the traditional wheel steering mechanism is complex, inconvenient to maintain, and not durable
