Abstract

The utility model relates to a clutch for a mixed electric vehicle, which is composed of a mechanical clutch, wherein a speed sensor is arranged on one side of the mechanical clutch, a motor controller and a transmission device of the mechanical clutch are orderly and electrically connected; the motor controller is connected with a power source; the transmission device of the mechanical clutch is an air cylinder; an air inlet valve of the air cylinder is an electric valve, and is electrically connected with the motor controller; a clutch arm of the mechanical clutch is connected with a piston rod of the air cylinder. The utility model has the advantage that a speed sensor is used for accurately detecting motor speed; the air cylinder pushes the clutch according to the rotation speed, and controls a motor and an engine to engage and disengage; when the rotation speed of the motor and the engine is coincident, no impact engagement is realized. The utility model also has the advantages of reliable operation, low cost and convenient maintenance.

Description

The automobile-used clutch of hybrid electrically

Technical field:

The utility model relates to a kind of engine clutch of Motor Vehicle, particularly hybrid motor and is used to control separating and oncoming clutch between motor and the motor.

Background technique:

At present domesticly existingly come solenoidoperated cluthes to be used for hybrid electric vehicle the pneumatic mode that combines with hydraulic pressure, but the control system of clutch is too complicated, comprise a cover pressurized oil system, and utilize oil cylinder to promote oil pressure wheel cylinder and oil pressure master cylinder, be that the oil pressure master cylinder promotes clutch at last, cost height not only, maintenance rate is also high.

Summary of the invention:

The purpose of this utility model is to overcome the above-mentioned drawback that existing hybrid electric vehicle is used for the clutch between motor and the motor, designs a kind of reliable operation, and cost is low, the motor that hybrid electrically easy to maintenance is automobile-used and the clutch of motor.

Technical solution of the present utility model is the automobile-used clutch of a kind of hybrid electrically, it is by mechanical clutch, reaching the speed probe of one side installation and the transmission device of electric machine controller and mechanical clutch electrically connects successively, electric machine controller connects composition with power supply, the transmission device of mechanical clutch is a cylinder, the suction valve of cylinder is a mortor operated valve, electrically connects with electric machine controller; The clutch arm of mechanical clutch connects with the piston rod of cylinder.

Description of drawings:

The automobile-used clutch configuration schematic representation of Fig. 1 the utility model hybrid electrically;

Fig. 2 hybrid electrically is automobile-used, the clutch configuration partial enlarged drawing.

Embodiment:

The utility model further specifies as follows in conjunction with specific embodiments referring to accompanying drawing:

Plant the electric vehicle clutch, referring to accompanying drawing 1,2, it is to connect motor 1 and motor 3 by mechanical clutch 2, and the transmission device of mechanical clutch 2 is a cylinder 6, and the clutch arm 4 of mechanical clutch 2 connects with the piston rod of cylinder 65 hinges, the suction valve of cylinder 6 is a mortor operated valve, it and electric machine controller 8 electrically connect, and electric machine controller 8 electrically connects with speed probe 7, and speed probe 7 is arranged near on 1 in the motor of mechanical clutch 2, electric machine controller 8 connects with power supply 9, by power supply 9 power supplies.

The utility model working principle is as follows:

By speed probe 7 detection of engine rotating speeds, tach signal is delivered to electric machine controller 8, electric machine controller 8 sends the clutch working signal according to rotating speed and makes electronic suction valve work, switch on or off the gas circuit of cylinder 6, make cylinder 6 work, its piston 5 bars promote clutch arm 4 separates or joint mechanical clutch 2: when motor 3 rotating speeds are lower than motor 1 idling, clutch 2 separates, motor 3 does not connect with motor, and motor 3 works independently, and hybrid electric vehicle is in operation under the electric-only mode; Surpass the idling of motor 1 when motor 3 rotating speeds, clutch 2 engages, and motor 3 connects with motor 1, powered vehicle jointly, and hybrid electric vehicle is under the combination drive pattern and moves.

The utility model advantage is accurately to detect motor speed by speed probe, by the clutch of cylinder according to rotating speed promotion Clutch Control motor and motor, when both rotating speeds are consistent, realizes not having the joint of impact, reliable operation, and cost is low, and is easy to maintenance.

Claims

1, the automobile-used clutch of a kind of hybrid electrically, it is by mechanical clutch, reaching the speed probe of one side installation and the transmission device of electric machine controller and mechanical clutch electrically connects successively, electric machine controller connects composition with power supply, the transmission device that it is characterized in that mechanical clutch is a cylinder, the suction valve of cylinder is a mortor operated valve, electrically connects with electric machine controller; The clutch arm of mechanical clutch connects with the piston rod of cylinder.
