Problems solved by technology

During the trial production of the prototype of the three-wheeled electric vehicle, the applicant adopted the technical scheme of combining the guide plate with the bushing and the shock absorber in the rear axle connecting device, and found that the steel plate guide plate is easy to bend or even break when braking. Vehicle driving poses a great safety hazard
The applicant later tried to solve this problem by increasing the thickness of the steel plate and adopting the method of stacking multiple steel plates, but this also affected the longitudinal deflection function that the front part of the steel plate should have, and would further damage the guide plate when the shock absorber was installed Hinge strength with frame
Moreover, the rear axles of the above-mentioned inventions all adopt the whole axle, and the two rear wheels are installed on the same axle, and the rear axle rotates during driving. This structure cannot install a hub motor on one side of the rear axle.

Abstract

The invention discloses a backshaft connecting device of a tricycle or a quadricycle. The backshaft connecting device comprises guide plates, a left connecting rack and a right connecting rack symmetrically arranged, connecting pipes, a bearing piece or a damper and a backshaft; the two connecting racks are transversely and fixedly connected with the connecting pipes; the front end of each guide plate is provided with a sleeve; the rear part of the guide plate is fixedly connected with the middle part of the connecting pipe; the lower end of the bearing piece or the damper is hinged with the connecting racks; the backshaft is arranged in the middle parts of left connecting rack and the right connecting rack; the guide plate on the front side and the rear side of the front connecting pipe is at least provided with a transverse reinforcing rib; and the longitudinal middle part of the guide plate between the sleeve and the reinforcing rib is at least provided with a longitudinal reinforcing rib. The backshaft connecting device has a simple structure, high intensity and prominent functions and can mount motors of different types. The backshaft connecting device can be widely used in a common tricycle or a minitype quadricycle, is convenient to detach, can greatly shorten the packing size of the tricycle or the quadricycle and is favorable for reducing packing and transportation cost.

Description

technical field [0001] The invention relates to a rear axle connection device of a vehicle, in particular to a rear axle connection device of a tricycle or a four-wheel vehicle. Background technique [0002] Chinese patents ZL 03126879.X and ZL 200410027852.6 disclose a rear axle connecting device of a miniature four-wheel vehicle and a light tricycle. The device can greatly simplify the frame structure of a tricycle or a four-wheel vehicle, occupy small space, and have light weight. The device is easy to process, and can be screwed with the main frame, which is easy to disassemble, so that the connecting device between the main frame and the rear axle can be packaged separately, so that the packaging volume of the tricycle or four-wheel vehicle can be greatly reduced, which is beneficial to reduce Packing and shipping costs. [0003] But above-mentioned invention still has some defectives. During the trial production of the prototype of the three-wheeled electric vehicle...
