Description

Hand full pull force flexible shaft operation mechanism

One. technical field

The utility model relates to the automobile variable speed steering unit, discloses the hand full pull force flexible shaft operation mechanism that a kind of automobile variable speed is handled usefulness especially, and the speed change that is applied to the automobile rear-engine is handled.

Two. background technology

At auto trade two kinds of steering units are arranged at present, first effector connects the hard connection that drives the change speed gear box transmission by two cover stiff rods and universal-joints, and to be effector be flexible coupling by two push-and-pull flexible axles are direct drive another kind.

Existing push-and-pull flexible axle mechanism realizes transmission by the push-pull effort of two push-pull cables, this system is in the defective that exists essence aspect the conveying thrust, the one flexible axle is when playing thrust, the outer steel band pillar of flexible axle can be loose, the formation transmission accuracy is on the low side, exists a certain amount of idle travel, along with the increase of pot life, idle travel influences the correctness of operation also along with increase.Its two accumulation along with the thrust times of exercise causes the cable core distortion, reduces greatly service life can only reach about 200,000 times.

Three. summary of the invention

The purpose of this utility model: be to solve the above many disadvantages that push-and-pull flexible axle mechanism exists, a kind of hand full pull force flexible shaft operation mechanism is disclosed, for all kinds of passenger vehicles provide a kind of simple in structure, easy for installation, handle light and handy, service-strong high precision, noiselessness, the effector of durable, low consumption power by force.

This reality is novel to be to realize like this, the hand full pull force flexible shaft operation mechanism that a kind of speed change that is applied to the automobile rear-engine is handled, comprise rocking arm, universal-joint, connecting rod and coupling, it is characterized in that: it also comprises curved effector of operator's saddle and the swing type mechanism that is contained on the change speed gear box, between effector and swing type mechanism with 3---4 flexible axles are connected, described effector comprises upper bed-plate 1 and the cross joint 3 that is contained on the upper bed-plate 1, rocking arm 2 by the installation of cross joint with hole and ring washer location, and be installed in fixing axle 7 on the rocking arm 2 with elastic cylindrical pin, on rocking arm 2, use two axles 4 of bolt; The swing type mechanism that is contained in change speed gear box comprises revoliving arm 10, and is contained in the axle 12 on the revoliving arm 10, uses the bearing seat 11 that rotates by antifriction-bearing box on the axle 12.Hand full pull force flexible shaft operation mechanism comprises upper and lower base, a T font rocking arm that is installed on the upper bed-plate, the universal rotary parts that one cover cross joint is formed, be installed on the rocking arm location cross joint and with the flexible axle of bolt, wrap in the protective cover of outside, sealing band on the Up/down base, and be installed in the handle that clamps with bolt on the rocking arm.

The change speed gear box revoliving arm comprises a twin-stage revoliving arm, is contained in the bearing seat on the revoliving arm, forms with the antifriction-bearing box of ring washer location in bearing seat.

Principle of work of the present utility model is summarized as follows: pull handle 9, drive rocking arm 2 and make the flexible axle action, flexible axle pulling revoliving arm 10 and bearing seat 11 drive change speed gear box engage a gear shaft 13 and rotate, and select gear shift work thereby change speed gear box work is finished.

Obviously, the utility model steering unit only carries pulling force, because flexible axle does not carry thrust when implementing gear selecting gear shift work, therefore the outer pillar of flexible axle does not stress, make manipulation light and handy more and accurate, long service life reaches about 1,000,000 times, simple in structure, sleeve mechanism all adopts indoor installation, is directly installed on the base plate, makes easier for installation.Describe below in conjunction with accompanying drawing.
