Description

Technical Field

[0001] This utility model belongs to the field of steering wheel technology, and in particular relates to a centrally located steering wheel control mechanism for a three-wheeled vehicle. Background Technology

[0002] The advantages of tricycles lie in their compact size, light weight, and small turning radius. Compared to trucks, tricycles are more environmentally friendly, economical, and highly maneuverable, making them suitable for short-distance operations. Traditional tricycles typically use handlebars for steering, which can be heavy and inconvenient to steer under heavy loads, making them difficult to operate. This can lead to driver fatigue during long journeys. Furthermore, the handlebars on tricycles are unstable, and in special circumstances, the steering may suddenly become uncontrollable, potentially causing an accident. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the prior art, this utility model provides a centrally mounted steering wheel control mechanism for tricycles, which installs a steering wheel on the basis of a tricycle with steering wheel pedals, and turns the tricycle by rotating the steering wheel.

[0005] The protective component includes a protective cover and a fixing ring. The protective cover is movably fitted onto the steering wheel. The inner side of the protective cover has multiple sets of sponge layers spaced apart. The outer side of the protective cover has an absorbent layer that can absorb sweat from the palms. The fixing ring has multiple sets and is movably fitted onto both ends and the middle of the protective cover.

[0006] The fixing ring has an elastic material in the middle and Velcro at both ends.

[0007] The turbine steering assembly includes a second rocker arm, a turbine steering gear, a front mounting plate, and a rear mounting plate. The front mounting plate and the rear mounting plate are both mounted on the three-wheeled vehicle frame. The turbine steering gear is mounted on the front mounting plate and the rear mounting plate. The second rocker arm is connected to the turbine steering gear via a nut.

[0008] The turbine steering assembly further includes a steering shaft head, a rocker arm, a universal ball joint, a universal ball joint, and a connecting rod. The steering shaft head is fixed to the front fork with bolts. The rocker arm is fixed to the steering shaft head with a grooved nut. The universal ball joint and the universal ball joint are respectively fixed at both ends of the connecting rod. The rocker arm is connected to the universal ball joint through a grooved nut, and the rocker arm is connected to the universal ball joint through a grooved nut.

[0009] The advantages of this utility model after adopting the above structure are as follows: it solves the problem of heavy steering and inconvenient operation of heavy-duty vehicles; the use of worm gear steering transmission has the characteristics of precise steering, small steering clearance, high driving stability, reliability and durability; it can be achieved by simple modification on the original steering wheel model, which is convenient to modify, has a high degree of universality and low cost; only simple tooling needs to be added, and the tooling mold has strong versatility; during the compression and stretching of the protective cover, the sponge layer can clean the surface of the steering wheel.
