Embodiment 1

[0022] Embodiment one, see figure 1 , an automobile shift clutch, comprising a master oil cylinder 1, a frequency regulating valve 2 and a working oil cylinder 3. The piston rod 11 of the master oil cylinder is connected with a clutch pedal 4 . The frequency regulating valve 2 includes a valve body 21 and a hole cover 22 . The valve body 21 is provided with an oil inlet 211 and an oil outlet 212 . The cylinder body 12 of the master oil cylinder is connected with the oil outlet 212 through the first oil pipe 6 . The oil inlet 211 is butted together with the cylinder body 32 of the working oil cylinder through the second oil pipe 5 . The piston rod 31 of the working oil cylinder is connected together with the clutch fork 7 .

[0023] see figure 2 , The valve body 21 is provided with an accommodating cavity 214 . The accommodating cavity 214 is cylindrical. The accommodating cavity 214 is provided with an oil inlet channel 213 and an oil outlet channel 216 . The oil inle...

Embodiment 2

[0025] Embodiment two, see image 3 , The difference with the first embodiment is: a shock absorber 218 and a magnet 219 are also provided in the oil outlet channel 216 . The damping plate 218 is adsorbed in the valve body 21 by the magnet 219 . When in use, the damping plate 218 can be taken and placed through the oil outlet 212, and this connection method can improve the convenience of installing and dismounting the damping plate. The damping plate 218 is arranged in the oil outlet channel 216 to improve the idling vibration damping effect of the present invention.

[0026] see Figure 4 , The cushioning sheet includes a substrate 2181 and a number of energy-absorbing rods 2182 . The energy-absorbing rod 2182 runs through the substrate 2181 . The energy-absorbing rod 2182 and the substrate 2181 are movably connected by a spherical fit. The energy-absorbing rod 2182 is provided with a through hole 2183 connecting two sides of the substrate 2181 .

Abstract

The invention relates to automotive parts, in particular to an automotive shift clutch comprising a master cylinder, an operating cylinder and a frequency modulation valve. The piston rod of the master cylinder is connected to a clutch pedal, and the piston rod of the operating cylinder is connected to a clutch fork. The frequency modulation valve comprises a valve body provided with an oil inlet, an oil outlet and an accommodating cavity. The accommodating cavity is provided with an oil inlet channel communicated with the oil inlet and an oil outlet communicated with the oil outlet. An energy absorption block with the elastically deformable surface is arranged in the accommodating cavity, a gap for communicating the oil inlet channel and the oil outlet channel is arranged between the energy absorption block and the accommodating cavity, the oil outlet is connected to the master cylinder, and the oil inlet is abut-connected to the operating cylinder. The invention aims to provide a clutch frequency modulation valve and an automobile shift clutch with the same, and solve the problem that obvious vibration occurs when a clutch pedal is stepped when an automobile starts in a manner of idle rotation.

Description

technical field [0001] The invention relates to automobile parts, in particular to a clutch frequency regulating valve and an automobile shifting clutch with the valve. Background technique [0002] The shift clutch is installed between the engine and the transmission, and its function is to gradually combine the engine and the transmission, so as to ensure that the car can start and accelerate smoothly. Now most cars generally use diaphragm spring pressure plate, step on the clutch pedal when starting and high-speed shifting, the clutch pedal drives the main cylinder, the main cylinder drives the sub-cylinder (also known as the working cylinder), and the sub-cylinder drives the clutch fork , The clutch fork connects the release bearing with the pressure plate. The clutch of this kind of structure is disclosed in the Chinese patent No. 012634700, the authorized announcement date being July 17, 2002, and the patent document titled "automotive clutch electro-hydraulic con...
