Abstract

The utility model relates to an automatic clutch for electric automobiles, which consists of a driven drum, a clutch bearing, a driving disc, a clutch shaft, a friction block (foot), a positioning pin, a reset spring, a stress application rod, a cam of the stress application rod and a positioning pin. The utility model uses the centrifugal force produced by the rotation of a motor for driving the clutch to realize the separation/engagement of the motive power from/with a locomotive. The utility model has the advantages of simple structure, easy manufacture, low cost, small size, light weight, reliable performance, environment protection, energy saving and the like.

Description

The electric vehicle automatic clutch

Technical field

The utility model relates to the novel electric vehicle automatic clutch of transport facility automobile, particularly environmental protection and energy saving

Background technique

Traditional electric automobile in the market; comprise hybrid vehicle; field vehicle; golf cart; dumping waggon; fork truck etc.; energy-conserving and environment-protective, but the speed of a motor vehicle is slow, and anxious acceleration performance is poor; continuous journey is short; the electric vehicle that wind group produces during with Shandong is an example, 100 kilometers of mileagess of continuation, 41.5 kilometers of speed per hours; because traditional electric automobile all adopts speed-regulating controller; there is not the gear case; clutch, gear ratio is fixed, and travels when going up a slope; starting belongs to the overload starting; motor starting under no load electric current greater than operating current 2-3 doubly, rise sometimes motionless, even damage speed-regulating controller; cause automobile bad on the way; if speed-regulating controller is protected shutdown automatically, automobile is reset also needs certain hour (because of speed-regulating controller needs cooling), so also causes traffic congestion easily.

Summary of the invention

The purpose of this utility model provides a kind of electric vehicle (contain mix power) automatic clutch, and it is that the centrifugal force that relies on motor to rotate to produce drives clutch and the separating and engage of the power realized and locomotive.

The technological scheme that the utility model solves is: this electric vehicle automatic clutch is made up of driven drum, clutch bearing, driving disc, clutch shaft, brake pad (hoof), locating stud, spring, extension lever; Afterburning cam and locating stud are housed on extension lever, the centrifugal force that this clutch relies on motor to rotate to produce drives clutch and realizes separating of power and locomotive and engage, when motor slowly starts low-speed running, centrifugal force is little, driving disc and driven drum are in separated state, when motor speed improves, centrifugal force increases, when centrifugal force greater than extension lever, during the elastic force of return spring, extension lever is that circular movement is outwards made in the center of circle with afterburning cam and since extension lever shoulder rod principle, the motion of afterburning cam is far longer than the elastic force of return spring, is that the center of circle engages to driven drum extruding thereby make brake pad (hoof) with the brake pad locating stud.

The utility model electric vehicle automatic clutch has simple in structure, easy to manufacture, with low cost, advantage such as volume is little, in light weight, reliable performance, environmental protection and energy saving.

Description of drawings

Fig. 1 is an electric vehicle automatic clutch structural drawing;

Fig. 2 is an electric vehicle automatic clutch sectional view.

Embodiment

Elaborate below in conjunction with drawings and Examples.

At Fig. 1, a driven drum 1 is arranged among Fig. 2, clutch bearing 2, driving disc 3, clutch shaft 4 is housed on the driving disc 3, brake pad (hoof) 5, brake pad (hoof) 5 is provided with locating stud 6, one end of return spring 7 is contained on the brake pad (hoof) 5, the other end connects extension lever 8, the other end of extension lever 8 is provided with afterburning cam 9, afterburning cam 9 is provided with cam orientation pin 10, this electric vehicle automatic clutch, the centrifugal force that relies on motor to rotate to produce drives clutch and realizes separating and engaging of power and locomotive, when motor slowly starts low-speed running, centrifugal force is little, and driving disc 3 is in separated state with driven drum 1, when motor speed improves, centrifugal force increases, centrifugal force is during greater than the elastic force of extension lever return spring 7, and extension lever 8 is that circular movement is outwards made in the center of circle with afterburning cam 9 and since extension lever 8 shoulder rod principle, the motoricity of afterburning cam 9 is far longer than the elastic force of return spring 7, is that the center of circle engages power and locomotive to driven drum 1 extruding thereby make brake pad (hoof) 5 with piece locating stud 6.

Claims

1, a kind of electric vehicle automatic clutch, comprise driven drum (1), clutch bearing (2), driving disc (3), clutch shaft (4), brake pad (5), locating stud (6), return spring (7), extension lever (8), it is characterized in that: extension lever (8) is provided with afterburning cam (9), and afterburning cam (9) is provided with locating stud (10).
