CS217482B1 - Gear lever set especially for passenger cars - Google Patents

Abstract

The invention solves the design of the gearshift lever mounting, especially for passenger cars, located mainly on the floor of the vehicle. The essence of the invention lies in the fact that the gearshift lever is mounted in a bracket made of a suitable plastic material in a ball bearing with several weakening grooves, facilitating the assembly of the gearshift lever, and the setting spring is slid onto a ribbed pin formed as part of the bracket and is secured by a washer and teeth formed at the end of the ribbed pin, which have inclined assembly leading edges. The swinging movement of the gearshift lever is transmitted to the rod mounted slidingly in the bracket by means of a sleeve, which is slid onto the rod with an overlap, and at the point of flattening of the rod there is a driving pin with teeth and inclined assembly edges, while the end of the gearshift lever fits into the opening of the sleeve with a spherical part. The invention can be used in the construction of motor vehicles or in the field of machine control in general.

Description

2

It is an object of the invention to provide a complete steering lever, particularly a passenger car, which is located predominantly in the vehicle floor. The design of the vehicle seat is made up of simplicity and technology, material and energy costs, and labor-intensive manufacturing while maintaining good function and reliability.

A number of radiation lever mounting solutions are known. The shift lever performs substantially swinging motion about the center of rotation and is disposed in a ball bearing formed in a bracket bolted usually to the floor of the vehicle. wherein the rod itself acts as a swinging or non-linear motion. The adjusting spring maintains the neutral position of the radiation lever. The basic body of the mechanism is a bracket in which the rod bearings are also stored. The bracket is especially made of 1'high aluminum alloy, which is a disadvantage. Its production is energetically and technologically demanding from the point of view of casting, the casting has to be mechanically machined. It has no suitable properties. The ball bearing must be divided from the mounting lugs, which is usually constructed with a lid, screwed together by a cube. The mounting of the adjusting spring and also the connection of the sleeve to the drawbar are solved with numerous connecting elementary elements, which manifests itself in the manufacturing workmanship and assembly and, ultimately, in the gear lever pricelist. In order to maintain the necessary lubrication of the sliding surfaces.

The above-mentioned drawbacks are eliminated by the arrangement of the shift lever assembly according to the invention, wherein the lever lever bracket, the spherical ball bearing, the rib of the adjusting spring and the bearings extend the integrated plastic assembly, the non-split ball bearing being placed in the center of the bracket, the rib of the adjusting spring protrudes from the bracket between the ball bearing and one of the rod bearings, the rod bearings located at the ends of the brackets having two-sided set-up rims for gripping the plastic lids. It is a further object of the invention to provide a non-split ball bearing with at least thrombids, the walls of which are parallel to the adjusting lever and the bottom of the grooves at the level of the ball bearing. The ribbed stud is guided with at least three longitudinal ribs and terminates with at least two cogs, between which is a transverse groove. Furthermore, a preferred embodiment of the invention is that a ring is provided above the spherical bearing for gripping the sleeve as part of the bracket, and a protrusion with a hollow-shaped cavity formed below the spherical ball bearing is formed. part of the bracket to limit the shift of the gear lever.

By using a plastic material for the shift lever bracket with other elements, a single ball bearing, a ribbed stabbing spring, and a rod bearing, an integrated unit is formed having both good friction properties on the friction surfaces and a lower weight compared to other materials at sufficient strength, resistance to corrosion, abrasion resistance, dimensional stability of a sufficient thermal range, as well as substantial flexibility, which is particularly advantageous for assembly. The production of such a composite is substantially more economical, resulting in lower energy demands in the production of plastic materials than metals. Another advantage lies in the smaller number of connecting elements, which is reflected in the lower workload of production and assembly of the assembly.

In the accompanying drawing, a specific embodiment of the switch assembly according to the invention is shown, wherein in FIG. 1 the shift lever assembly is shown in section A-A of FIG. 2 and FIG. 2 complete gear shift lever in the podium.

The gear lever assembly is housed in a plastic material compartment 1 of suitable properties that is screwed to the car floor 3. The shifting lever 4 is pivotably supported by its ball face 6 in a non-denelegular bearing 7 with four grooves 8. The stiffening spring 9 is supported on both sides of the shift lever 4 by its straight ends 10 extending up to the arm 11 the bracket 1 and is slid on the ribbed pin 12 with the longitudinal ribs 13, ending with two cogs 14 with inclined leading edges, the pin itself being weakened by the groove 15 and the cog 14 preventing the pad 30 from falling out. a bracket 1 with double-sided cover slip surfaces 19, elastically mounted on a shoulder 18 of bearings 17. The trim lever is covered by a sleeve 27 attached to the bracket by a rim 28 which is formed as part of the bracket 1. Under the ball bearing 7, a protrusion 21 is formed with a pyramid-shaped cavity 22 as part of a console 1, limiting the maximum swinging lever 4.

To assemble the gear lever assembly 4, press a certain force into the non-split ball bearing with a pressing force, where the plastic material surrounds the ball surface 6 and the locking lever against the axial movement by the elasticity of the ball surface 6 of the shift lever 4 of the dogul bearing 7.

The method of accommodating the gear lever assembly can also be advantageously used in other conveying devices, not only in passenger cars.
