Description
Technical Field
The invention belongs to the technical field of intelligent electric vehicles, and particularly relates to a torsion supporting structure of a front fork part of a front wheel drive intelligent electric vehicle.
Background
Generally, the front fork of the electric vehicle comprises a left fork part and a right fork part, a fork opening is formed in each fork part and is in a flat opening shape, flat square parts at two ends of a motor shaft are installed in the fork openings when the front wheel motor is driven, and then the two ends of the motor shaft are locked through nuts. When the motor outputs torque, the motor shaft generates torsion to the fork opening part, and the torsion acts on the shock absorber on the front fork, so that the shock absorption effect is achieved.
When the electric vehicle is driven by the front wheel motor, the front fork of the electric vehicle can bear larger torsion, so that the fork opening of the front fork is easy to deform and damage, and the front wheel motor is easy to fall off after the fork opening of the front fork deforms and damages, thereby causing safety accidents. The front fork in the current market does not have a front wheel torsion supporting structure, or the front wheel torsion supporting structure is installed more complicatedly, and manufacturing cost is high, and production quality is difficult for controlling scheduling problem, and to the above-mentioned problem, the applicant provides a torsion supporting structure that simple structure is reliable, production installation is convenient, production quality is controllable.
Disclosure of Invention
In view of the above deficiencies of the prior art, the present invention provides a torque support structure with simple and reliable structure, convenient production and installation, and controllable production quality, so as to share the torque of the motor, avoid damaging the fork opening of the front fork, and prevent the front wheel motor from falling off.
In order to achieve the purpose, the technical scheme of the invention is as follows:
a torsion supporting structure of an intelligent electric vehicle comprises a front fork, wherein a left fork piece and a right fork piece are arranged at the tail end of the front fork, a fork opening is formed in each fork piece, torsion supporting gasket grooves are formed in the inner side and/or the outer side of each fork piece, torsion supporting gaskets corresponding to the torsion supporting gasket grooves are arranged in the torsion supporting gasket grooves, each torsion supporting gasket is of an eccentric structure or any non-rotary structure, and the strength of each torsion supporting gasket is greater than that of each fork piece; the torque supporting pad is provided with a closed flat square hole or an open flat square groove, and the flat square part of the motor shaft is matched with the closed flat square hole or the open flat square groove.
According to the invention, the torsion supporting gasket is additionally arranged on the side surface of the front fork opening part, the flat square part of the motor shaft is arranged in the flat square holes or the flat square grooves of the front fork opening and the torsion supporting gasket, so that the torsion of the motor shaft is shared and borne, and meanwhile, the torsion supporting gasket has higher strength, so that the damage of the front fork opening can be greatly reduced, the situation that the front wheel motor falls off after the front fork opening is deformed is prevented, and the safety performance of the electric vehicle is improved; in addition, from the structure, the invention only adds the gasket groove on the side surface of the front fork piece, and the torsion supporting gasket is arranged in the gasket groove, so that the structure is simple and reliable, the production and the installation are convenient, and the production quality is controllable.

Because what outside torsion supported the gasket and adopted is closed flat square hole, what inboard torsion supported the gasket and adopted is open type flat square groove, during the installation, install inboard torsion support gasket in the inboard gasket groove earlier, then go into the motor shaft card in the flat square groove of inboard torsion support gasket, install outside torsion support gasket in the gasket groove in the outside again, make the motor shaft pass the flat square hole of outside torsion support gasket, the nut locking of rethread both sides at last, can accomplish the installation of front wheel, except being convenient for go into the front fork structure with the motor shaft card, still owing to receive the restriction in closed flat square hole, the condition that the front wheel motor drops has been prevented better.
Further, the fork mouth piece is made of an aluminum alloy material, and the torsion supporting gasket is made of a stainless steel material. Because the front fork mouth piece adopts high strength aluminum alloy, can reduce weight, simultaneously, torsion support pad adopts stainless steel, and intensity is higher than the aluminum alloy, compares other materials (for example titanium alloy etc.) simultaneously, and material cost is lower.
Further, the torsion support gasket is fixed in the torsion support gasket groove by any one of bolting, riveting or welding. Because the torsion support gasket is fixedly arranged in the gasket groove in the modes of bolt connection, riveting or welding and the like, the torsion support gasket can be better prevented from rotating after being stressed.
Furthermore, a front mudguard support mounting hole is formed in the fork opening piece. When the front mudguard support is installed, the lower end of the front mudguard support is locked on the fork opening piece through a bolt and a nut.
Further, a line card used for fixing the motor line is arranged on the fork opening piece. When the cable clamp is installed, the front wheel motor cable is fixed in the cable clamp.
Compared with the prior art, the invention has the beneficial effects that:
1. bear front wheel motor torsion in sharing, alleviate the damage to the front fork mouth, prevent that the front wheel motor from droing, improved intelligent electric motor car's security.
2. The structure is simple and reliable, the production and installation are convenient, and the production quality is controllable.
3. The dismouting is convenient, connects reliably.
4. The front wheel installation, the installation of the front mudguard, the motor wire clamping, the shock absorption and other functions are integrated, and the universality and the interchangeability are good.
