A ratchet-type auxiliary device for starting a vehicle on a slope

Abstract

The invention discloses a ratchet wheel type auxiliary device for vehicle hill starting, and belongs to the field of vehicle control devices. The ratchet wheel type auxiliary device for vehicle hill starting comprises a ratchet wheel, a locking claw and a pull rod; the ratchet wheel is installed on a power input shaft of a transmission, the locking claw is installed on a shell of the transmission and further provided with a friction plate matched with the ratchet wheel, and the pull rod is connected with the first gear and the reverse gear of the transmission; when the transmission is at any gear except for the first gear and the reverse gear, the pull rod pushes the locking claw to enable the locking claw and the friction plate to be separated from the ratchet wheel; and when the transmission is at the first gear or the reverse gear, the pull rod contracts, the locking claw falls under the effect of gravity to enable the friction plate to be in contact with the ratchet wheel, the ratchet wheel drives the locking claw to rotate during reverse rotation, and therefore the locking claw is meshed with ratchets of the ratchet wheel. According to the ratchet wheel type auxiliary device, the ratchet wheel and the locking claw are additionally installed on the vehicle transmission so as to assist in vehicle hill starting, vehicle sliding on a hill is effectively prevented, the structure is simple, operation is easy, the refitting cost is low, and convenience is brought to popularization.

Description

technical field [0001] The invention relates to an auxiliary device for starting a vehicle on a hill, more specifically, a ratchet type auxiliary device for starting a vehicle on a hill. Background technique [0002] Starting on a hill is a technique that is difficult to master in car driving, especially when starting on a steep slope. When the car is parked on an uphill, in order to prevent the car from rolling back, the driver must apply the handbrake while depressing the brake. Only when the car stops steadily, and when starting on a slope, the coordination of the handbrake, clutch, and accelerator is very important. If the handbrake is released too late, the engine will stall, and if the handbrake is released too early, the vehicle will slide backwards. If the driver does not control the accelerator and clutch well, it is very likely that the vehicle will slip backwards, and even cause a traffic accident. [0003] In order to solve the above-mentioned problems when the ...
