Abstract

The motor 3 is mounted on a frame or chassis member 1 of the vehicle by means of a mounting plate 32 which has an upwardly extending section coupled to the frame inwardly thereof and a downwardly extending section which is coupled via the frame to the casing of the final drive 8 which is detachably mounted outwardly of the frame. <IMAGE>

Description

SPECIFICATION Vehicle This invention relates to hydrostatically driven vehicles and is primarily concerned with the manner in which the hydraulic motor is mounted thereon.
Heretofor, two alternative methods have been employed for mounting running motors on hydrostatically driven vehicles. In one arrangement, the running motor was mounted on the inside of a reduction gear casing fitted to the vehicle body frame or chassis by means of bolts In the alternative arrangement, the running motor was mounted by means of bolts inside the vehicle body frame independently of the reduction gear casing which was fitted to the outside thereof.
We have found both these arrangements to suffer disadvantages. In the first arrangement, if the final reduction gear casing is disconnected from the running gear for removal from the vehicle body frame, then the running motor tends to drop by its dead weight and means must be provided for holding the running motor with obvious difficulties and inconvenience in maintenance and when making repairs. In the second mounting arrangement, fine finishing of the inner and outer surfaces of the vehicle body frame are necessary in order to obtain accurate fitting. This requires considerable working labour.
The present invention has arisen out of our work seeking to improve the arrangements for mounting motors in hydrostatically driven vehicles.
In accordance with the present invention, there is provided a hydrostatically driven vehicle, including a hydraulic pump; a hydraulic motor connected with the hydraulic pump in a closed loop and adapted to be driven thereby, the motor being mounted on a frame or chassis member of the vehicle by means of a mounting plate fixedly secured to said motor and having an upwardly extending section and a downwardly extending section, the upwardly extending section being coupled to said frame inwardly thereof; and a final drive having a casing detachably mounted outwardly of said frame; the downwardly extending section of said mounting plate being coupled to said final drive casing via said frame.
The invention is hereinafter more particularly described by way of example only with reference to the accompanying drawings, in which: Figure 1 is a top plan view of a hydrostatically driven vehicle in which the motor and related parts are shown in solid lines and other parts of the vehicle are shown in phantom lines or omitted altogether; Figure 2 is a side elevational view thereof; and Figure 3 is a cross-sectional view taken along the line Ill-Ill of Figure 2.
The vehicle shown in the drawings has a body frame 1 and two sets of independent hydraulic pumps 2,2 mounted on the left and right sides thereof. Disposed behind the hydraulic pumps 2, 2 are two sets of hydraulic motors 3,3 arranged to be driven by the fluid under pressure discharged from the pumps. Each ofthe hydraulic motors 3,3 has a projecting, integrally formed mounting plate 3a extending internally alongside the vehicle body frame 1. The mounting plate 3a has bolt holes 3b formed in its corners. A bolt 4 is inserted through each of the upper holes 3b so that the mounting plate 3a may be fixedly secured to triangular brackets 5 fitted to the outside face of the vehicle body frame.These brackets 5 each have screw threaded holes 5a formed in the ends thereof. Threadably engaged with the screw threaded holes 5a are the leading ends of mounting bolts 6 inserted from the inside of the vehicle body frame 1 for fixedly securing the brackets 5 on the outside surface of the vehicle body frame 1. Thus the upper part of the mounting plate 3a of the hydraulic motor 3 is fitted to the vehicle body frame 1 by the brackets 5. The lower part of the mounting plate 3a is fitted to a final reduction gear casing 8 by means of mounting bolts 7 inserted into bolt holes 3b and extending through spacers 9.
The final reduction gear casings 8, each enclosing a final reduction gear having an input shaft, not shown, connected to an output shaft 3c of each hydraulic motor 3, are also coupled by bolts, not shown, to the outside of the vehicle body frame 1.
With the above described arrangement, when it is desired to remove the final reduction gear casing 8 from the vehicle body frame 1, this can be achieved independently of the hydraulic motor 3 simply by removing the mounting bolt, not shown, and the bolts 7 inserted in the lower corners of the mounting plate 3a. There is no possibility of the hydraulic motors 3 dropping when the final reduction gear casings 8 are removed in this fashion, so enabling maintenance and repairs to be carried out much more easily. In the described arrangement, the hydraulic motors 3 are fitted to the vehicle body frame 1 through the brackets 5 which are previously fitted to the vehicle body frame 1.The hydraulic motors 3 can thus be readily mounted in position, and since the brackets 5 are mounted on the outer side of the body frame 1, finishing work need only be conducted on this outside surface, thus reducing the number of manufacturing steps as compared with the previous arrangements referred to hereinabove.
1. A hydrostatically driven vehicle, including: a hydraulic pump; a hydraulic motor connected with the hydraulic pump in a closed loop and adapted to be driven thereby, the motor being mounted on a frame or chassis member of the vehicle by means of a mounting plate fixedly secured to said motor and having an upwardly extending section and a downwardly extending section, the upwardly extending section being coupled to said frame inwardly thereof; and a final drive having d casing detachably mounted outwardly of said frame, the downwardly extending section of said mounting plate being coupled to said final drive casing via said frame.
2. A vehicle according to Claim 1, wherein said upwardly extending section is coupled to said frame by means of a bracket, first bolt means mounting said bracket to the outer surface of said frame, and
