Hydraulic cylinder as well as drive unit for accelerating and braking vehicle

Abstract

The invention discloses a hydraulic cylinder which consists of a cylinder body, a piston, a push rod and an oil storage case, wherein a slide valve arranged inside the cylinder body has a punch hole and the push rod and can control hydraulic operation. The invention discloses another type of automobile accelerating and braking drive unit which comprises a pedal, a booster, a brake master cylinder and an accelerator guy cable, wherein the pedal [17] is connected with the accelerator guy cable [27] through a clutch means, and is connected in turn with the booster [34], the hydraulic cylinder [1], an oil pipe [35] and the brake master cylinder [36] through the push rod [33]; the brake master cylinder [36] adopts fluid-pressure drive; a control device, which ensures that the slide valve [6] can close an oil through hole [13], open the channel of an oil outlet hole [15] and can realize the clutch of a guy cable rod [31], is arranged between the pedal [17] and the hydraulic cylinder [1]. The hydraulic cylinder has the function that a user can use just one pedal to control acceleration and braking operation; moreover, the hydraulic cylinder can realize automatic braking protection when an operation mistake occurs and has convenient use and reliable installation.

Description

technical field [0001] The invention relates to a hydraulic cylinder, in particular to a hydraulic cylinder with a built-in slide valve. The invention also relates to an automobile accelerating and braking driving device. Background technique [0002] At present, most of the hydraulic cylinders that people set up are typical models, which include: oil cylinder, piston, push rod, oil storage tank and so on. Its main function is to use oil as a force transmission medium, and it is widely used in modern industrial technology. However, this traditional typical model has a single function and fails to bring into play its more useful functions. [0003] Modern cars use one pedal for acceleration and one pedal for braking. The driver must frequently move his right foot up and down, left and right between the two pedals when operating, which is not only inconvenient to operate, but also easy to make mistakes in emergency situations. , there is a great security risk. A few years ...
