Four-wheel Drive, Power Available at Three Auxiliary Points, and an Engine of Unusual Design, Form Outstanding Features of a Now Rover Product
IN the Land-Rover, which has just been announced, The Rover Co.. Ltd., of Solihull, Birmingham, has combined the functions of a light van or a car and trailer, with those of a light tractor, thus providing a single vehicle which will meet the majority of needs of the small farmer, or provide for the stand-by requirements of owners of larger farms. The vehicle also offers wide scope for works transport, and as a portable source of power.
These widely varying requirements are catered for by a sturdily built machine, powered by a four-cylindered petrol engine, linked to a transmission system providing twoor four-wheel drive (alternative sets of gear ratios at will), a choice of power take-off arrangements, and a front — winch. Mounted on this multi-purpose chassis is a utility-type body in which noncorrodible light-metal panelling is freely used, with stout steel reinforcements at all points liable to rough treatment.
The power unit, which is of 1,595 c.c. capacity (69.5 mm. x 105 mm.), has an unusual arrangement of overhead inlet and side-exhaust valves, and is, in fact, similar to that used in the recently introduced Rover "60" private car. Unusual features of the engine design comprise an inclined split between block and head, which makes possible a valve layout embodying an exhaust valve in the cylinder block at
55 degrees from the vertical, and an inlet valve in the head at 20 degrees from the vertical. Operation is front a single camshaft, the exhaust valves being actuated through the medium of short :rockers, and the overhead inlet valves by conventional push rods and rockers.
This arrangement makes for good breathing and valve cooling, excellent anti-pinking qualities and mechanical stiffness. The power output is 50-55 b.h.p. at 4,000 r.p.m.
With the needs of stationary work in view, special attention has been paid to adequate cooling, the fan being cov,led to ensure a good cooling draught through the radiator block. The latter is exceptionally well protected in that it is not only situated well back from the front of the vehicle, but is also protected by a substantial metal pressing, and by a stout meshed grille; the headlamps also share this protection.
In unit construction with the engine, A32
is a conventional dry-plate clutch, a four-speed synchromesh gearbox and the transfer box which is on the offside of the main gearbox. This complete assembly is off-set in the frame by approximately 21 ins, to provide space for the transfer box, and for the drive shafts leading fore and aft to the front and rear axles respectively.
The drive to the transfer box is taken via a pair of intermediate pinions which mesh with a further pair of gearwheels on the transfer-box mainshaft. Of the two wheels on the latter, one (which
gives the high set of ratios) is mounted freely on its shaft, and is provided with external dogs corresponding to the splines on which the second wheel is slidably mounted.
Thus, by moving the sliding pinion in one direction the high-rate pinion becomes locked to the transfer-box naainshaft, bringing the upper set of ratios into operation. Moving the pinion in the other direction brings its teeth into mesh with the appropriate intermediate pinion, and provides the low set of ratios.
