Flexible-shaft variable speed manipulator for heavy truck

Abstract

The invention discloses a flexible-shaft variable speed manipulator for a heavy truck, which is one of the important parts in a speed changing system of the heavy truck and is used for realizing gear shifting of a speed-changing gear box through driving of a flexible shaft. The flexible-shaft variable speed manipulator comprises a flexible-shaft fixing seat, a support of a horizontal state and a gear selecting and shifting manipulation mechanism connected on the support, wherein the flexible-shaft fixing seat is arranged on one end of the support and is integrated with the support. The flexible-shaft fixing seat comprises a first horizontal block, a second horizontal block and a connecting plate, wherein the first horizontal block and the second horizontal block are integrated, the connecting plate is connected between the first horizontal block and the second horizontal block, the side faces of the first horizontal block, the second horizontal block and the connecting plate are all planar, the bottom of the first horizontal block is provided with a first groove for accommodating a gear selecting flexible shaft, the bottom of the second horizontal block is provided with a second groove for accommodating a gear shifting flexible shaft, and the openings of the first groove and the second groove both face right downwards. The flexible-shaft variable speed manipulator provided by the invention can be used for simultaneously carrying out mould opening on the support and the flexible shaft fixing seats for molding, therefore, the labor intensity of workers is effectively reduced and the production efficiency is improved.

Description

Flexible shaft shift manipulator for heavy trucks Technical field: The invention relates to a vehicle speed change control system, in particular to a flexible shaft speed change manipulator for heavy-duty trucks which can realize gear shifting by driving a flexible shaft. Background technique: The flexible shaft transmission manipulator is one of the important components in the transmission system of heavy trucks, and it is generally installed under the cab of heavy trucks. At present, there is a flexible shaft speed change manipulator in the prior art. As shown in Figures 4 and 5, the flexible shaft speed change manipulator includes a gear selection and shift control mechanism, a flexible shaft fixing seat 107 and a horizontal support 102. The shaft fixing seat 107 is located at one end of the bracket 102 and is integral with the bracket 102. The flexible shaft fixing seat 107 is respectively provided with a first groove 105 and a second groove 106 for positioning the gea...

AI Technical Summary

Problems solved by technology

Although the above-mentioned flexible shaft shifting manipulator has been widely used, it still has the following defects in the actual production process: since the flexible shaft fixing seat 107 is inclined to a certain extent relative to the horizontal bracket 102, in other words, the flexible shaft fixing seat 107 There is an included angle with the bracket 102 in a horizontal state, and the openings of the first groove 105 and the second groove 106 provided on the flexible shaft fixing seat 107 are all facing sideways, and the front side 110 of the flexible shaft fixing seat 107 and the The rear side 111 is arc-shaped, so the flexible shaft fixing seat 107 and the horizontal bracket 102 cannot be molded at the same time. Mold opening is carried out along the inclined direction perpendicular to itself. During production, workers generally can only place two additional inserts assembled together in the mold of the forming bracket 102, and use the inserts to form the flexible shaft fixing seat 107 separately. After the production is completed, the worker needs to open the mold of the bracket 102 first, and then manually separate the two assembled inserts, that is, open the mold of the flexible shaft fixing seat 107. Obviously, this production method will greatly increase the Increase the labor intensity of workers and reduce production efficiency
