Problems solved by technology

[0002] The front fork part is in the front part of the bicycle structure, and its upper end is connected with the handlebar part. The ordinary front fork is only damped by a single spring, and the shock absorption effect is poor. The fixed sleeve on the car body is directly pressed on the fixed shaft. , the fixed sleeve is directly connected to the surface of the crown during the rotation process. After long-term use, the wear between the fixed sleeve and the crown is serious, and it is easy to break after deformation and damage.

Embodiment 1

[0029] Such as Figure 1-7 As shown, in this embodiment, a kind of electric vehicle front fork with shock absorbing function is provided, comprising a shoulder 2 and a shock absorbing assembly installed at both ends of the shoulder 2, and the middle part of the shoulder 2 is far away from the shock absorbing assembly. Fixed shaft 15 is installed on one side, and fixed shaft 15 is rotated and installed in the inside of fixed sleeve 1, and fixed sleeve 1 is fixed on the vehicle body, and fixed shaft 15 is connected with handlebar, and handlebar controls fixed shaft 15 to rotate;

[0030] The shock absorbing assembly includes an inner shaft 3 mounted on the prong 2 and a casing 4 sleeved outside the inner shaft 3, a bridge is installed between the two casings 4, and the bridge is used to support the two casings 4 , to prevent its relative position from changing, the bottom of the housing 4 is plugged with a bottom shaft 8, the bottom shaft 8 is a truncated cone, the inner wall of...

Embodiment 2

[0032] combine Figure 5-6 , on the basis of Embodiment 1, the following embodiment is proposed: the fixed shaft 15 is inserted into the inside of the fixed sleeve 1, the fixed sleeve 1 is fixed with the electric vehicle body, and one side of the fixed sleeve 1 is installed with a side Column 17, side column 17 is the medium that is used for being connected with car body, and described fixed shaft 15 is provided with a plurality of steps, and each described step is a conical surface, and the fixed shaft 15 conical surfaces and fixed sleeve 1 are provided with There are gaps, and several uniformly arranged rollers 16 are installed at each gap, and the rollers 16 are circumferentially arranged on the cone surface, and the rollers 16 on the fixed shaft 15 are in contact with the inclined surface on the inner wall of the fixed sleeve 1, so that the fixed shaft 15 and the fixed shaft are in contact with each other. The rotation between the sleeves 1 is smoother, and the supporting ...

Abstract

The invention discloses an electric vehicle front fork with a damping function, which belongs to the technical field of electric vehicles and comprises a fork shoulder and damping components mounted at two ends of the fork shoulder. The damping assembly comprises an inner shaft installed on the fork shoulder and a shell connected to the outer portion of the inner shaft in a sleeving mode. The fixed shaft is inserted into the fixed sleeve, a plurality of steps are arranged on the fixed shaft, each step is a conical surface, a gap is formed between the conical surface of the fixed shaft and the fixed sleeve, and a plurality of uniformly arranged rollers are mounted at each gap. When the outer shell is subjected to transverse force, the inner shaft and the piston have transverse supporting force, transverse deformation is not prone to being generated between the inner shaft and the outer shell, the resistance borne by the piston is larger when the piston slides downwards, and when the axial sealing column slides to the hole bottom of the longitudinal hole and the wheel is blocked, the buffering effect is achieved; and the fixing sleeve is protected.

Description

technical field [0001] The invention relates to a front fork of an electric vehicle with a damping function, belonging to the technical field of electric vehicles. Background technique [0002] The front fork part is in the front part of the bicycle structure, and its upper end is connected with the handlebar part. The ordinary front fork is only damped by a single spring, and the shock absorption effect is poor. The fixed sleeve on the car body is directly pressed on the fixed shaft. , During the rotation process, the fixed sleeve is directly connected with the surface of the crown. After a long time of use, the wear between the fixed sleeve and the crown is serious, and it is easy to break after deformation and damage. Contents of the invention [0003] Aiming at the above-mentioned problems in the prior art, the present invention provides a front fork of an electric vehicle with a shock-absorbing function, which can realize a front fork of an electric vehicle with a goo...
