SU37499A1 - Transmission to the drive wheels self-propelled carts - Google Patents

Description

There are carts for driving on mountain roads, the wheels of which always remain upright, regardless of the lateral inclination of the track, due to the fact that they are fixed on the vertical rods of the hinge parallelogram located in the transverse plane of the cart; the other two sides of the parallelogram are rotated on the pins fastened in the hull of the cart along its longitudinal axis. Therefore, the vehicle body can also rotate on the specified axles, always maintaining its vertical position, even if the wheels of one side of the vehicle are higher than the wheels of the other side. The subject matter of the present invention is the transmission of rotation in such self-propelled vehicles (tractors, etc.) from the motor shaft to the leading, vertically moving vehicle wheels, consisting in that the equalizing mechanism (differential) is located on the axle on which the vehicle body is rotated and an articulated parallelogram, and connected by a Gaul chain to a drive shaft, and by means of other chains and a system of gear wheels, with the drive wheels of a cart. With this transmission device, the coupling of the motor shaft to the drive wheels remains always constant and unchanged; as if following a transversely inclined path and did not change along

the height of the position of the wheels in relation to the hull of the carriage in which the motor is located, with the usual for self-moving: carts parts.

In FIG. 1 shows schematically in the rear view one of the possible inclined positions of the wagon with the proposed gear; FIG. 2 and 3 - types of the transfer from behind and from above ;. FIG. 4 and 5 are a side view and a vertical section of the gear part related to the wheels; FIG. 6 and 7, two differential cuts.

The device of the proposed transmission is as follows. The differential of the carriage of the vehicle (Fig. B and 7) is installed on the same finger (pin) 5, which serves as the axis of the suspension of the carriage case on the lower long side / ball-parallelogram (Fig. 1); On the lateral vertical sides of it (rods x) 3, 3, drive wheels b, 6 are installed.

An asterisk / 2 (Fig. 2), seated on the drive shaft, with the help of an endless Gaul J4 chain transmits the rotation of a large (crown) sprocket 73 differential (Fig. 2 and 6) freely attached to the finger 5. By means of a crosspiece with J8 conical satellite sprocket 75 interlocks with two bevel gears / 9, constituting asterisks / 5 (5), which are one piece sa and also freely rotating on a finger 5. Through chains J6 and 16a (fig. 2) rotation from sprocket / 5 is transmitted to asterisks / 7, made in-one with bevel gears 20 (Fig. 4) and freely seated on pa tsah bottom side 23 of the hinge connection / parallelograia vartikalnymi with its two rods 3, 3. Each of the latter fastened to the transverse plane of the wagon fingers 26 and 28 (Fig 5). on the first finger are put on the components of one integer-bevel gear 2 /, coupled with the gear 20 on the finger 23, and the spur gear 22, acting on the large gear 24. The latter is mounted on the hub 27 of the second wheel 6 rotating by means of the rollers on the finger 28, which serves as the axis of the wheel.

To obtain rotation of both wheels 6 in the same direction, gears 20 must be coupled with gears 2 / from different sides for each wheel: if gears in one wheel are in front of gears 2 / along the length of the wagon, then in the other - from behind (Fig. 3 ).

Structurally, the main side / hinge parallelogram is made of .iB in the form of a corresponding form of a composite casing 30, 31 (Fig. 2 and 3), in which the differential with related gears 18, 19 and sprockets 13 and 15, chain gears 16 and 16a and asterisks / 7s gears 20.

The subject matter of the invention

Transmission to driving wheels, self-propelled carts fixed on vertical rods of the hinge parallelogram, the other two rods of which are pivotally fixed one above the other on the frame of the carriage, characterized in that the differential is located on the pin 5 (Fig. 1 and 2) of the hinge joint one of the rods with the frame and the satellites with the crosspiece of the satellites by means of a chain drive / 4 with a drive shaft, and the driven bevel wheels / I / by means of chain gears 76 and f6a (Figs. 2 and 3) are coupled with bevel gears 20, 20, mounted on fingers 23, 23 hinge the same articulation with vertical rods and coupled with bevel gears 2 /, 21, which communicate by means of a gear 22, 24 rotation of the wheels.
