Abstract

PURPOSE: To permit the braking when the transmission is in the neutral state to be automatically effected by connecting a transmission speed change operation pump and a braking cylinder for the drive section of the transmission via a speed change operation valve.
CONSTITUTION: When applied to a shovel car provided with a wheel type running device 1, an oil hydraulic pump P is provided in an interlocked relation to an engine 6, and a power shift transmission 10 is provided on the vehicle. An oil hydraulic motor M and an oil hydraulic pump P interlocked to each other are coupled to an input shaft 11 of the transmission 10, and a directional control valve V for forwardly and reversely driving the oil hydraulic motor M is provided on the side of a revolving base 4. Further, a speed change operation pump P1 and a braking oil hydraulic cylinder 33 in a brake unit 12 for wheels 1a are coupled to the input shaft 11 and piped to each other through a speed change operation valve V1. With the swinging operation of an operation lever 25 both the valve V and V1 are coupled in an interlocked relation through an interlock mechanism 20 such that the cylinder 33 is in a braked state in the neutral position of the transmission 10.
