Description

[Detailed description of the invention] This invention relates to an agricultural tractor, and the battery is mounted using an axle bracket with a center pin that supports the front axle, thereby increasing the versatility of the axle bracket and simplifying the structure. At the same time, the purpose is to improve the strength of the axle bracket.

In conventional tractors for seedbeds, the front axle is attached to the front end of the machine via an axle bracket, and the battery is mounted on the machine via a suitable frame, but this The mounting means has a complicated structure and is expensive.

The present invention was devised in order to address the above problems.The front half of the axle bracket, which has a center pin supporting the front axle at the bottom, is made wider than the rear half, and the upper part is placed on both sides of the axle bracket in the width direction. If the protruding parts are integrated, a flat part is provided on the inside of both the button protrusions on the front half to form a battery mounting part, and a flat part is provided on the inside of both the button protrusions on the front half to form a battery mounting part. A rear wall of the protruding part is formed, and the rear wall is shaped so as to serve as a receiving part for the rear part of the battery mounted on the mounting part, and the axle bracket is designed to increase the stiffness and strength, and to increase the weight. This battery is also characterized in that no special reinforcing structure is required, and by attaching the battery using the axle bracket, it is possible to simplify the structure and provide it at low cost.

The details of the present invention will be explained below based on the embodiments of the drawings.

In the figure, reference numeral 1 denotes the body of an agricultural tractor, and an engine 2 is fixedly supported at the front end of the body 1.

Reference numeral 3 designates a front axle bracket, and the bracket 3 has a substantially gate-shaped side section, and is formed by installing a center pin 5 between opposing walls 4, 4 of an open part of the gate shape. An axle 6 is fitted and supported, and a front wheel 7 is supported by the axle 6.

The front axle bracket 3 has a generally T-shape in which the front half buttoned in the longitudinal direction of the center pin 5 is wide and the rear half buttoned narrow. 8.8 is integrally provided, and in the front half of this bracket 3, planar portions 9, 9 are provided inwardly from both projecting portions 8.8 to appropriate lengths. A gently sloped surface 10 that is concavely curved downward is formed in the middle portion of the bracket 3, and the front half of the bracket 3 forms a battery mounting portion 11! A rear wall 12 of the overhang 8 formed on the way from the wide part to the narrow part serves as a receiving part for the rear part of the battery.

Further, on the rear end surface of the front axle bracket 3,
A plurality of mounting pins 13 are provided protrudingly, and a plurality of pin holes 14 are formed on the front end surface of the engine 2 to face the pins 13. Each of the pin holes 14 is filled with caulking agent to secure the pins 13. By pressing, the front axle bracket 3 is directly fixed to the engine 2.

15 is a battery mounted on the battery mounting portion 11 of the bracket 3, and the battery 15 is the 7277130 battery.
It is placed on the measuring surface part 9°9 between the two overhanging parts 8, 8, and is mounted with its rear part in contact with the rear wall 12 of each of the overhanging parts 8, and approximately at the middle of the bracket 3. The screw punches 17 are supported by metal fittings 1616 fixed on both sides of the battery 15, while a cross-section shaped support fitting 18 is attached to the front upper corner of the battery 15.
The battery 15 is fixed on the mounting portion 11 by inserting the screws 17 into both sides of the metal fittings 18 and screwing the nuts 19 onto the tips of the screws 17.

A pedestal 20 is attached to the upper surface of the rear half of the bracket 3, and a radiator 21 is supported on the pedestal 20.

In the figure, 22 is an opening formed in the center of the front axle bracket 3, and 23 is a front damper attached to the front surface of the bracket 3.

As described above, the present invention makes the front half of the upper part of the axle bracket, which has a center pin that supports the front axle in the lower part, wider than the rear part, and has overhangs that protrude upward on both sides of the axle bracket. In addition to providing the parts in one piece,
A rear wall of the overhang is formed on the overhang of the front half to serve as a rear receiving part for the battery, so that the battery can be mounted on the axle bracket, which means that the axle bracket is originally highly rigid. Because it uses
Moreover, by forming the rear wall of the projecting portion and the projecting portions on both sides in the width direction on the axle bracket, the rigidity of the axle bracket can be increased and the strength can be improved;
Furthermore, since the battery can be mounted within the space formed by the rear wall of the overhang and the overhang on both sides in the width direction, it can be mounted stably, and even heavy batteries can be supported without the need for a special reinforcing structure. Therefore, the versatility of the axle bracket is increased, the overall structure can be simplified, and it can be provided at low cost.
