Overturn preventing device for vehicle with two front wheels

Abstract

The invention discloses an overturn preventing device for a vehicle with two front wheels. The vehicle with the two front wheels comprises a frame with a hollow positioning piece, a front wheel unit corresponding to the positioning piece, and a steering unit used for controlling the front wheel unit. The overturn preventing device comprises a tilting unit pivoted to the positioning piece, and a locking unit used for locking the tilting unit, wherein the locking unit is provided with a hydraulic locking mechanism integrated on the tilting unit. The tilting unit is controlled to tilt relative to the positioning piece through the hydraulic locking mechanism, so that the tilting unit is locked in time to be prevented from tilting relative to the positioning piece so as to avoid the overturn of the vehicle with the two front wheels; and the device is simple in integral structure, the installation procedure can be effectively simplified and the waste of space can be reduced.

Description

technical field [0001] The present invention relates to a vehicle with two front wheels, in particular to an anti-dumping device for a vehicle with two front wheels. Background technique [0002] Existing motorcycles have a rear wheel and a front wheel positioned on the same axis as the rear wheel. Although this unstable design has brought about agility in operation, it has relatively sacrificed riding The stability at the time makes the rider have to rely on his own sense of balance to control the motorcycle to avoid the motorcycle from tipping over. Therefore, those who are slightly older or have a poor sense of balance are not suitable for riding a motorcycle. [0003] In order to increase the stability of existing motorcycles, relevant industry players have been actively developing hybrid (hybrid) vehicles that combine the stability of automobiles and the handling of motorcycles in recent years. The three-wheeled vehicle ", and the "three-wheeled rolling vehicle with tw...

Problems solved by technology

[0004] In order to make the two front wheels swing or rotate relative to the ground under control at the same time, the above-mentioned vehicles all utilize a four-bar linkage to simultaneously control the two front wheels to swing or rotate relative to the ground. However, as everyone knows, the four links of the four-bar linkage The joints are pivoted to each other. Therefore, at low speed or when parking, the four-bar linkage mechanism will sway and cause the vehicle to topple over. Therefore, related companies have developed an anti-sway device as disclosed in the Taiwan Patent Application No. 94102972 , using the locking disc and the locking caliper arranged in cooperation with each other, and a motor for pulling the locking caliper to lock the four-bar linkage mechanism in time to prevent the vehicle from falling due to the swing of the four-bar linkage mechanism. However, due to the anti The locking disc and the locking caliper of the rocking device must be set correspondingly, which is cumbersome to install. In addition, the locking caliper needs to be driven by a motor, so many components affect the space configuration of the vehicle.
