Inclination control device for two front wheels of vehicle

Abstract

An inclination control device for the two front wheels of a vehicle comprises a main frame, a steering assembly, two wheel sets, two upper connecting rods, two lower connecting rods, two steering pull rods, a rocking connecting rod, two shock absorbers, a brake pad and a brake. A lower connecting rod and an upper connecting rod are respectively pivoted between the main frame and the left and right wheel sets, a steering pull rod is respectively pivoted between the steering column and the left and right wheel sets, a rocking connecting rod is arranged above the upper connecting rod, shock absorbers are respectively arranged above the two lower connecting rods, the lower ends of the shock absorbers are pivoted to the lower connecting rods, and the upper ends of the shock absorbers are pivoted to the two sides of the rocking connecting rod and penetrate between the upper connecting rod and the steering pull rod. A brake pad is arranged above the rocking connecting rod, and a brake is arranged adjacent to the brake pad. When a vehicle needs to be parked, the brake is started to lock the brake pad arranged on the rocking connecting rod, so that the two shock absorbers and the two lower connecting rods are limited by the rocking connecting rod and do not rotate any more, the two lower connecting rods do not rock any more, free movement of the left and right parallelogram connecting rods is limited, the two wheel sets stop and do not rock any more, and the vehicle can stably stand and park in more than three wheels.

Description

technical field [0001] The invention relates to a vehicle tilt control device, in particular to a tilt control device suitable for the front two wheels of a vehicle. Background technique [0002] Today's commonly used personal vehicles generally include automobiles and motorcycles. The vehicle in the form of a motorcycle is a vehicle driven by an engine or a motor and mainly uses a handle to control the direction of two, three or four wheels. The characteristics of simplicity, convenient movement and low price have become the most commonly used means of transportation at present. [0003] At present, consumers on the market like convenient two-wheeled motorcycles. For riders with poor balance and control ability, they are prone to lose control and overturn when they brake suddenly in a sudden situation, especially when driving on wet slippery or uneven gravel roads.

Problems solved by technology

[0003] At present, consumers on the market like convenient two-wheeled motorcycles. For riders with poor balance and control ability, they are prone to lose control and overturn when they brake suddenly in a sudden situation, especially when driving on wet slippery or uneven gravel roads. Riders with better control ability are often unable to avoid losing control and turning over

[0004] The main reasons for discussing its overturning are as follows. Because two-wheel motorcycles only have one wheel at the front and rear, the stability provided is not enough. It is necessary to rely on the rider to correct the steering and change the center of gravity of the body to balance the car so that it does not overturn. Those who must have the ability to quickly respond to the situation and control the balance can keep the car from turning over

The main reason is that the two-wheeled motorcycle loses control and rolls over when the road is wet and slippery. The tires lose grip on the ground, which makes it impossible to make steering corrections to balance the car.

[0005] In addition, vehicles with two front wheels have appeared on the market at present, which are motorcycles equipped with a articulated quadrilateral structure and two independent front suspension systems. Generally speaking, the bottom end of the shock absorber of this vehicle is pivotally connected The caliper component is fixed to the lower seat of the shock absorber directly above the wheel shaft on the swing arm. This structural design will cause the shock absorber to bear the strong rotational thrust generated by the caliper component when the caliper component brakes. Therefore, the shock absorber needs to be replaced. The high-strength structural design increases the volume, weight and cost of the shock absorber

[0006] For example, the front two-wheel motorcycle of the new M441617 patent case in Taiwan, China, is connected through the hydraulic oil circuit of the left and right shock absorbers, so the manufacturing cost is high and the reliability of the system is worrying.

In addition, the front two-wheeled motorcycles produced by Piago and Yamaha companies use many parts and high cost, and the high quality of the system makes the suspension response slow

In addition, when the front two-wheel motorcycle is parked, it often shakes up and down because the left and right wheel sets of the front two wheels are not on the same plane, so it is easy to topple over, which is not very ideal, and there is still room for improvement
